Nexus phones support OTG. If the Nexus 7 does as well, carry your movies on a thumb drive and play them directly from there. You can also move them to your internal memory if you wish.

I think I paid 6 bucks for my OTG/USB adapter (the same adapter needed to connect a mouse or keyboard).

Question, have you used USB flash drives on your Android device? I was just reading around and it appears there are some folks who had peripherals working okay with OTG but had trouble mounting storage devices.

Perhaps it's a power issue? I imagine that a tablet would struggle to power a USB-powered hard disk drive.

Since the advent of Android 2.3 I have had no problems with my newer flash drives. All the problems I have run into have had to do with power requirements. I have had little success with USB powered hard drives.

I use the Transcend and Kingston version of these and have had no problems.

For those that are interested I'm attaching a thumbnail of the USB pinouts. As you can see the only difference between the regular and the OTG cable is that pin 4 and 5 are tied together. If the tablet senses a ground on pin 4 it knows that it should act as a host usb port if not then act as a device port. Simple and easy/cheap to implement.
